1'0 aZZwhom it may concern.-

Be it known that I, MARCUS J. BARTLETT,

a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain. new and useful Improvements in Veneer Coiling and Nailing Machines, ofwhich the folabout the drum and to provide suitable means A whereby said nailing devices may be readily adjusted longitudinally of the drum in order to properly secure the stifiening-hoops in the desired positions along the drum.

Other objects of difierent features of my invention will be understood from the following description with reference to the accompanying drawings, in which- Figure 1 is a front elevation, partly broken away, of a machine constructed according to my invention. Fig. 2 is a transverse section of the same along the line 2-2 of Fig. 1, also partly broken away. Fig. 3 is an end elevation of the same. Fig. 4 is an end elevation of the saw mechanism for trimming the ends of the package. Fig. 5 is an elevation of a portion of the nail-feeding mechanism. Fig. 6 is a top plan of a portion of the mechanism shown in Fig. 5. Fig. 7 is an elevation of the mechanism for rocking the nail-trays. Fig. 8 is a top, plan of a nail tray and the adjacent guide-plates. Fig. 9 is a bottom plan of a part of the frame of one of the nailing devices. 'Fig. 10 is a diagram showing the arrangement of levers for tripping the plan-- gers of the nailing devices. Fig. ll is a front being woundupon the drum.

In the construction shown the drum-shaft Fig. 12 is a. plan of a sheet of veneering with its stifienv lis journaled in the members 3 and4 of thesupporting-frame at one end and is steadied at its other end by the gate 5, which is hinged to the member 6 of the supporting-frame. A

collapsible drum 8 is rigidly mounted on the 'shaft l at a point midway between the mema'bers 6 and 7 of the supporting-frame.

cured to a shaft 15, which extends longitudinally through the drum and which is journaled in the spiders 16, which brace the part 9 of the shell. The spiders 17, which sup- .port the part 10 of the shell, are rigidly secured to the shaft 1.

The shaft 15 is provided at one end with a handle 18, by means of which said shaft may be turned to bring the cams 14 to bear upon the lugs 19 on the supporting-spider of the part 10 of the shell.

The aperture 12 is beveled, as shown, for the purpose which will be hereinafter described.

The counter-shaft 20 is journaled in the supporting-frame and is connected with the shaft 1 by means of the gears 2land 22. The shaft 20 has mounted on one end a wheel 23, which is adapted to receive motion through frictional contact with' a similar wheel 24,- mounted on a movable shaft 25. Power is supplied to the shaft by means of a belt communicating with the pulley 26. The shaft 25 is mounted in pivoted bearings 27 and 28. The bearing 27 is secured to the member 4 of the frame, and the bearing 28 is slidably mounted in the member 3 of the frame. The wheel 24 is normally held out of engagement with the wheel 23 by gravity. Downward pressure .upon the treadle 29 of the lever 30 raises the lever 31 and moves the wheel 24 into Contact with the wheel 23. A compression-roller 32 is journaled in crossheads 33, which are mounted so as to bevertically slidable in the members 6 and 7 of the frame. The oross-heads33 areconnected by a brace 34. A lever 35, carrying a weight 36 the strap 39. The cross-bar 38 rigidly connects the members 6 and 7 of the frame. A

second lever 40 is fulcrumed at 41 to the cross-bar 38 and is connected to the lever 35 by means of the strap 42.

A horizontal shaft 43 is rigidly secured between the members 6 and 7 and has mounted thereon a plurality of castings 44, which serve as frames for the nailing devices. The castings 44 are secured against rotation by the feather 45 and are secured against sliding longitudinally of the shaft 43 by means of the set-screws 46. A pair of plungers 47 are mounted so as to be vertically slidable in the channels 48 of the castings 44. Each of the plungers 47 is provided with a spring 49, which is seated in a counter-bore 50 in the upper end of said plunger and bears against the stop 51, so as to normally urge the plunger 47 downwardly. Each of the plungers 47 is rigidly connected by a strap 52 to a slide 53, which is mounted so as to be vertically slidable along the groove 54 of the castings 44. A shaft 55 extends horizontally between the members 6 and 7 and is journaled in each of the castings 44. Keyed to the shaft 55 are a plurality of hooks 56, each of which is suitably located to engage a notch 57 in one of the slides 53. A lever 58 is secured to one end of the shaft 55 and is adapted to control the angular position of said shaft. The spring 59, connecting the lever 55 with a lug 60 on the member 7, normally urges the hooks 56 into engagement with the notches 57. The end 61 extends downwardly into suitable position to engage pins 62 on a sleeve 63, which is keyed to the shaft 1. The end 64 of the lever 58 is used when it is desired to trip the hooks 56 by hand. I

Below each of the plungers 47 extend a pair of jaws 65, which are pivoted to the castings 44, so as to be movable toward and from each other and are normally held together by means of a spring 66. Directly beneath the. plungers 47 the adjacent surfaces of the jaws 65 are so formed as to form a tapering aperture 67, adapted to support a nail with its point downwardly.

The stop 51 is .pivoted to the castings 44 at 68 and is vertically adjustable by means of the cap-screw 69, thereby regulating the tension on the spring 49.

At the rear part of each of the castings 44 is secured a bracket 70, to which is horizontally pivoted at 71 a nail-tray 72. A horizontal shaft 73 is journaled to each of the brackets and has secured thereto a plurality of levers 74. Each of the lovers 74 is located -in a suitable position to engage a roller 75, secured to one of the nail-trays 72.

A counter-shaft 76 is journaled in the upper part of the members 6 and 7 and is connected.

with the counter-shaft 20 by means of the chain belt 77 and the sprocket-wheels 78 and 79. An eccentric 80 is mounted on the shaft 76 near one end and connected with a pin 81 on the disk 82 at the end of the shaft .73. The

throw of the eccentric 80 is considerably less than the diameter of the circle described by the revolution of the pin 81, so that the shaft 73 will not describe a complete revolution, but will reciprocate through a certain angle, thus causing the lever 74 to alternately'raise and lower the nail-tray 72. The bottom of each of the nail-trays 72' is provided with a pair of slots 83. In front of each of the nailtrays 72 is a downwardly-inclined guide-plate 84, which is provided with slots 85, which meet the slots 83. The agitation of the nailtray 72 causes the shanks of some of the nails to protrude through the slots 83, the nails being thus supported by their heads. The end 86 of the tray 72 is suitably slotted to permit the passage of said nails out of the tray 72 and along the slots of the guide-plate 84. Secured to the under side of the guide-plate 84 is a vertical plate 87, provided with slots 88. These slots are adapted to permit the passage of nails along the grooves 85. A second plate 89, similarly slotted, is slidably secured to the plate 87. The spring normally urges the plates 87 and 89 into the position shown in Fig. 5, where the slots 88 and 90 do not register with each other. The plate 89 is further provided with a finger 91, adapted to prevent more than one nail at a time from entering the slot 90. A shaft 92 is slidably mounted on the brackets 70 and is provided with fingers 93, which engage the plate 89. The shaft 92 is caused to move in the direction of the arrow 94 by means of the bellcrank lever 95, which connects with one of the vertically-reci procating slides 53 by means of the link 95. The spring 97 tends to return the shaft 92 to its normal position. Nails accumulating back of the plates 87 and 89 are retained in the grooves 85 by means ofa coverplate 98, secured above the plate 84. The lower ends of the slots 85 lead to the tubes 99, which conduct the nails to the jaws 65. A bar 100 is mounted on the guides 101, which are secured to the castings 44. The bar 100 is vertically movable and is adapted to raise the slides 53'to the position shown in Fig. 2. A regular vertical reciprocating movement is communicated to the bar 100 by means of the connecting-rods 96. The connecting-rods 96 are rigidly secured to the guide members 102, which encircle the shaft 76 and are pivoted at 103 above the shaft 76 to the straps 104 of the eccentrics 105.

A shaft 106 is journaled in the lower part of the frame and carries thereon a pair of arms 107, to which is journaled a second shaft 108. A weighted lever 109 is secured to the shaft 106 and is adapted to hold the various parts in the position shown. Thelever 110 is provided for turning the shaft 106. A pair of circular saws 111 are mounted on the shaft 108 and are used for trimming Zthe ends of the packages formed on the drum 8. Power is communicated to the shaft 108 by means of a belt engaging the pulley 112.

The sprocket 79 is loose on the shaft 20 and ICC is connected to same by the clutch 114. 1 This permits the drum to be revolved independently of the nailer mechanism.

The operation of the device shown is as follows: The veneering 113 is lightly tacked together in the form of a rectangular sheet with longitudinal bands 115 thereon, as shown in Fig. 11. The drum 8 is turned until the aperture 12 is at the top. The lever 40 is now drawn downwardly, raising the weighted lever35 and with it the compression-roller 32. The drawings show the compression-roller 32 in its raised position. The edge 116 of said sheet of veneering is pushed into the aperture 12 of the drum and against the lugs 19. The

castings 44, carrying the nailing devices, will have been previously set to such position along the shaft 43 that the nailing devices will be brought into alinement with the desired position of the hoops 115 of the package. The lever 40 is now released and the compression-roller 32 is forced downwardly against the drum 8 by means of the action of the weight 36. The pulley 26 is connected by means of a belt with line-shafting, which is not shown in the drawings and may be assumed to be running, the direction of its rotation being indicated by the arrow 117 in Fig. 3.

The operator now steps upon the treadle 29 and through the action of the system of levers 30 and 31 raises the wheel 24 into frictional contact with the wheel 23, causing the drum 8 to revolve in the direction of the arrow 117. The revolution of the drum 8 carries with it the sheet of veneering, and the downward pressure of the com pression-roller 32 causes said veneering tobe tightly wound around the drum 8 until the two ends of the veneering are caused to overlap at the upper side of the drum 8. At the proper instant the treadle 29 is released and thewheel 24 allowed to fall away from the wheel 23. This immediately stops the revolution of the drum 8. While the drum 8 is revolving, the chain belt 77, connecting the sprocket-wheels 78 and 79, turns the shaft 76 and through the connection of the eccentrics 105 with the connecting-rods 96 causes the bar 100 to reciprocate vertically along the guide 101. The plunger-tripping mechanism is arranged in the device shown, so as to operate at five regular intervals during a single revolution of the drum 8.

gage the lever 58, and consequently trip the hooks 56 when the plungers 47 are adjacent to the points on the periphery of the drum 8 at which it is desirable to drive nails. adjustment of the collar 63 permits same to be turned slightly on the shaft 1 and set so as to cause the pins 62 to trip the nailing mechanism,so as to drive the nails at slightlydifierent points of the periphery of the drum, and thus avoiddriving any of the nails too near to the overlapping edge of the veneering. When the hooks 56 are released from 50 upon the lever 58.

ing the drum with the shaft 76 is so arranged that the bar 100 will be in its lowest position The collar 63 is adjusted. upon the shaft 1, so that the pins 62 will en-l tion of the plungers 47 and permit the pas-' sage of said nails and plungers. The spring 66 tends to force the jaws 65 together as soon as the plunger 47 is withdrawn. After the plungers 47 have been forced downwardly the reciprocating bar 100 engages the slides 53 and raises them,together with the plungers 47, to their uppermost position, when the catches 56 are urged into engagement with the notches 57 through the action of the spring The gearing connectwhenever the plungers 47 are driven downwardly through the engagement of the lever 58 with one of the pins 62.

The nail-feeding devices operate as follows: Each of the nail-trays 72 is partly filled with nails,which are kept in agitation through the action of the lever 74 against the roller 75, the lever 74 being caused to reciprocate vertically through an arc of a circle by means of its hereinbefore-described connection with the shaft 76. While the nails in the tray 72 are being agitated, some of their shanks will fall through the slots 83 and will be delivered along the slots 85 of the guide-plate 84,where they will be stopped by the plates 89 of the retaining mechanism. (Shown in Figs. 5 and 6.) At each operation of the plungers 47 the shaft 92 is caused to slide in the direction94 by means of its bell-crank-lever connection with one of the slides 53, and the finger 93 moves the plate 89 until the slots are in alinement with the slots 88. The finger 91 being rigidly secured to the plate 89 moves with said plate and enters the space between the two nails which are adjacent to the plate 89, thus permitting only one nail ata time to fall through the slot 88. The slot 85 delivers said nail to one of the nail-chutes 99, by which it is carried and delivered point downwardly into the aperture 67 between a pair of the jaws 65. It will thus be seen that only one nail will be delivered to each of the jaws 65 111 are thrown upwardly by means of the lever 110, so as to trim the edges of the package at the sides of the drum 8, the drum being caused to revolve and the clutch 114 being open.

It will be seen that numerous details of the device shown may be altered without departing from the spirit of my invention. I therefore do not confine myself to such details except as hereinafter limited in the claims.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a machine of the class described, the combination of a frame; a horizontally-dis posed shaft journaled in said frame; a collapsible drum mounted on said shaft; means for coiling veneering about said drum; a vertically-disposed plunger slidably mounted in said frame above said drum in suitable position for driving nails into the veneering on said drum; suitable means for supporting a nail below and in alinement with said plunger; means for feeding nails singly and in succession to said nail-supporting means; a spring normally urging said plunger down- Wardly; means for raising said plunger against the action of said spring; a movable catch for holding said plunger in its raised position; a spring normally urging said catch into engagement with said plunger; a lever secured to said catch and movable therewith; and a collar secured to said shaft and having thereon a projection adapted to engage said lever during the revolution of said drum and cause same to trip said catch and release said plunger, substantially as described.
